      <p>Creates a <a href="dart-collection/SplayTreeSet-class.html">SplayTreeSet</a> that contains all <code>elements</code>.</p>
<p>The set works as if created by <code>new SplayTreeSet&lt;E&gt;(compare, isValidKey)</code>.</p>
<p>All the <code>elements</code> should be instances of <code>E</code> and valid arguments to
<code>compare</code>.
The <code>elements</code> iterable itself may have any element type, so this
constructor can be used to down-cast a <code>Set</code>, for example as:</p>
<pre class="language-dart"><code class="language-dart">Set&lt;SuperType&gt; superSet = ...;
Set&lt;SubType&gt; subSet =
    new SplayTreeSet&lt;SubType&gt;.from(superSet.whereType&lt;SubType&gt;());

  for (final element in elements) {
    E e = element;
    result.add(e);
